Warning: Back up the seat grease fitting so only the safety vent cap will be removed from the fitting. Carefully
remove the safety cap from the seat grease fitting. NEVER remove the grease fitting when the valve is under
pressure.

3.

Remove safety vent cap from grease fitting. Attach grease gun connection onto grease fitting and inject
sealant. If injection of the sealant is difficult, flush the valve seats and attempt to inject sealant again.

4.

Repeat process for the second seat grease fitting as applicable, or the stem fitting. Replace safety caps on
all grease fittings.
